* vt: break a couple of obsolete SCOish codes.Adam Borowski2013-09-26
| | | | | | | | | No modern terminal supports them, and SGR 38 conflicts with detecting xterm-256 colours. This also makes SGR 39 consistent with other popular terminals. Neither are used by ncurses' terminfo. Signed-off-by: Adam Borowski <kilobyte@angband.pl> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* hvc_vio: Do not override preferred console set by kernel parameterBen Hutchings2013-09-26
| | | | | | | | | | | | | | | | The original version of this was done by Bastian Blank, who wrote: > The problem is the following: > - Architecture specific code sets preferred console to something bogus. > - Command line handling tries to set preferred console but is overruled > by the old setting. > > The udbg0 console is a boot console and independant.

| | | | | | | | | | | | | | | Enabling the ARM DCC console and using without a JTAG connection will simply hang the system. Since distros like to turn on all options, this is a reoccurring problem to debug. We can do better by checking if anything is attached and handling characters. There is no way to probe this, so send a newline and check that it is handled.

One to watch out for in future. A number of driver specific fixes 1) at91 - fix a overflow in clock rate computation 2) dummy - Kconfig dependency issue 3) isl29018 - uninitialized value 4) hmc5843 - measurement conversion bug introduced by recent cleanup. 5) ade7854-spi - wrong return value. Some IIO core fixes 1) Wrong value picked up for event code creation for a modified channel 2) A null dereference on failure to initialize a buffer after no buffer has been in use, when using the available_scan_masks approach. 3) Sampling not stopped when a device is removed. Effects forced removal such as hot unplugging. 4) Prevent device going away if a chrdev is still open in userspace. 5) Prevent race on chardev opening and device being freed. 6) Add a missing iio_buffer_init in the call back buffer. These last few are the first part of a set from Lars-Peter Clausen who has been taking a closer look at our removal paths and buffer handling than anyone has for quite some time.

Do this by setting the character device's parent to the IIO device, this will cause the character device to grab a reference to the IIO device and only release it once the character device itself has been removed. Also move the registration of the character device before the registration of the IIO device to avoid the (rather theoretical case) that the IIO device is already freed again before we can add the character device and grab a reference to the IIO device. We also need to move the call to cdev_del() from iio_dev_release() to iio_device_unregister() (where it should have been in the first place anyway) to avoid a reference cycle. As iio_dev_release() is only called once all reference are dropped, but the character device holds a reference to the IIO device.

| | * iio: at91: fix adc_clk overflowJosh Wu2013-09-18
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | The adc_clk variable is currently defined using a 32-bits unsigned integer, which will overflow under some very valid range of operations. Such overflow will occur if, for example, the parent clock is set to a 20MHz frequency and the ADC startup time is larger than 215ns. To fix this, introduce an intermediate variable holding the clock rate in kHz.
